Thomas Bartholin has been much on my mind lately; in fact, I've been silently referring to him as "Thomas" (since he doesn't seem like a "Tom"--or a "Barty" for that matter).

On the unicorn is a rather scarce title, but sounds like it would be well worth the effort to find a copy to read (good thing I've been keeping up with my Latin). His thesis might be just the backing that modern purveyors of unicorn products are looking for to secure FDA approval.
